A Hong Kong-based JP Morgan spokeswoman said the bank was aware of the incident but it could not confirm at this stage whether the deceased was an employee of the bank. The bank is working with other parties including the police and the property manager of Chater House to follow up on the case, she added.

Just last month 39-year-old Gabriel Magee, also an employee of JP Morgan, fell to his death from the firm's European headquarters during rush hour in London.

Magee, a vice president in IT at the bank, landed on the ninth floor of the 33-floor building in Bank Street, in the busy Canary Wharf financial district. Police said that they were not treating his death as suspicious.
